Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR WG

The date or estimated date that the allergy or intolerance resolved. This is called abatement because of the many overloaded connotations associated with resolution.

Comment:

Age is generally used when the patient reports an age at which the allergy or intolerance abated. If there is no abatement element, the clinicalStatus can be used to convey whether allergy or intolerance has resolved or not. When abatementString exists, it conveys that the allergy or intolerance is abated.

Context of Use: Use on Element ID AllergyIntolerance
